Our results clearly show that two different articulations unite the parts of the bipartite cuneiform: the presence of cartilage is due to its participation in the diarthrodial joint, while the other articulation is a synfibrosis, a synarthrosis
that could experience closure due to membranous ossification, process in which no cartilage is involved (Manzanares et al., 1988).
(9) The main supporting structures include cranial and caudal cruciate ligaments, joint capsule, patellar ligaments, medial and lateral collateral ligaments, and menisci." (10-12) The proximal third of the fibula has a fibrous synarthrosis
with the lateral tibiotarsus by means of the interosseous ligament and is attached at the fibular crest by a bifurcated proximal tibiofibular ligament.
